l FEED-WATIER `REGULATOR FOR BOILERS.

Specicatio of Letters Patent. i

Patented Dee-5, vi905.

To all whom' t may concern:

Be it known that we, JEssn T. AvARY and EDGAR LONNIE THOMAS, citizens' "of the United States, residing at Ada, Chickasaw Nation, Indian Territory, have invented certain new andluseful Improvements in Feed- Water Regulators for Boilers; and we do declare the following tobe a full, clearfand eX- act description of the invention, such las will enable others skilled in t'he art to which it appertains to make and use the same. .t

This invention relates to improvements in feed-water regulators for steam-boilers.

-The object of the invention is to provide a device of this character which willv automatically control the admission or supply of water to the boiler.

A further object is to provide a valve for the devicewhich ,may be easily controlled while under heavy or light steam-pressure by the action ofthe regulating device.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed. Y v t In the accompanying drawings, Figure 1 -is a longitudinal vertical sectional view of lthe device, showing the application of the same to a boiler. Fig. 2 is an enlarged longitudinal sectional view through the steam throttle valve. view through the center ofsaid valve, and Fig. 4 is a similar view through one end of the same.

Referring more particularly to the drawings, 1 denotes a steam-boiler.

2 denotes the water-glass of the boiler,

said water-glassbeing of the usual construction and is connected with the lower portion `of the boiler by means of a water tube or pipe 3 and at its u per end is connected to the upper portion oi the boiler by means of a steam-pipe 4.

The Jfeed-water regulator consists of a vertically-disposed tank 5, which is preferably cylindrica in form and is connected at its lower end to the water Atube-orpipe 3 by means of a Water-pipe 6 and at its upper end is connected to the steam-pipe 4 by means of a pipe 7. Byv means of the connecting-pipes between the upper and lower ends of the water-glass tube andthe tank 5 the water in said tank and water-glass will attain the Fig, 3 is a cross-sectionalY same level as vthat in the boiler. Within the tank 5 is arranged a iioat 8, to the upper'and lower ends of which are connected upwardly and downwardly projecting guide rods or stems 9 and 10. The guide rods' or stems 9 and 10 are adapted to project through ystuffing-boxes 12, arranged in the upper and lower ends of the tank 5, and to the proj 'ec'tng end of theu Y alink 13, t e opposite end of which is connected to the lever or handle 14. A throttlevalve-15 is arranged in a steam-supply pi e 16,'which is connected to steamipe 4 at t e upper portion of the boiler. T e op osite en of said steam-pipe 16 is connecte with a pum 17, whereby when said valve 15 is 'open t -e pump 17 will be supplied with steam, thus operating the same, and by which meanswater will be pumped .into the boiler through a supply-pipe 18.

The throttle-valve 15 preferably consistsy of a shell or case 19, in the opposite sides of which are arranged inlet and discharge ports v2() and 21. In the casing 19 is arranged a per guide rod oristemis connected plug 22 is arranged a longitudinally-disposed nected a centrally-disposed transverse inletpassage 26, which when said plug isturned to the roper position will communicate with ,the i et-port 20 through the passage 27,

formed in the walls -of the valve-casing. Near the ends of the plug 22 are formed transversely-disposed discharge-passages 28, which extend through said plug in a plane at right angles to the plane of the passage 26. Thepassages 28 intersect andcommunicate with the longitudinal passage 25 in the plug 22 andopen into annular steam-chambers 29, formed in the opposite ends of the valvecasing and with which'communicate discharge-passages 30. The opposite ends 'of said passages 30 open into vthe dischargeport 21, formed in the side of the casing, and with which is connected the steam-supply 18,

which leads to the pump 17. To the projecting end ofthe valve-stem 23 is connected the lever or handle 14, said handle being connected by the link 13 to the upper end ofthe guide rod or stem 9 of the iioat 8, whereby when said float is raised and lowered by the passage or chamber 25, with which `is con- IOO l rising and falling of the Water in the boiler said valve will be regulated or closed, `thereby regulating the ioW of steam from the boiler to the um so that When the Water in the boiler as oWered to a danger-point the pump will be automatically started, thus forcing more Water into the boiler, as Will be understood. Y

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention Will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacriiicing any of the advantages of this invention.

Having thus described our invention,what We claim as new, and desire to secure by Letters Patent, is-

A valve for operation in a steam-pipe leading from a boiler to a pump and comprising a casing having chambers near its ends, passages leading to said chambers from the pump side of the steam-pipe, a bore connecting said chambers, a channel to connect the pump side of the steam-pipe with the bore, and a hollow turning plug for operation by a iioat, said plug having openings to communicate With the channel and being provided near its ends with openings communicating with the chambers in the casing.

In testimony Whereoi1 We have hereunto set our hands in presence of two subscribing Witnesses.
